Central heating - Wikipedia

Overview. Central heating differs from space heating in that the heat generation occurs in one place, such as a furnace room or basement in a house or a mechanical room in a large building (though not necessarily at the geometrically "central" point). The heat is distributed throughout the building, typically by forced-air through ductwork, by water circulating through pipes, or by steam fed

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

Orifice Meter - Types, Applications & Advantages | Aspire

Nov 10, 2018 · The liquid or gas whose flow rate is to be determined is passed through the orifice plate. This creates a pressure drop across the orifice plate which varies with the flow rate, resulting in a differential pressure between the outlet and inlet segments. This pressure drop is measured and is used to calculate the flow rate of the fluid or gas.
